INK-BOTTLE.

Specification of Letters Patent.

Patented Mar. 13, 1917.

Application filed April 21, 1916. Serial No. 92,740.

To all whom it may concern:

Be it known that I, Issac LAUTMAN, a citizen of the United States, residing at Fort \Vayne, in the county of Allen and State of Indiana, have invented certain useful Improvements in Ink-Bottles, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to improvements in pen point receiving stoppers for inkwells, one object of the invention being the provision of stopper which will permit the insertion of a pen point and provide a regular depth of dip for the pen point, and which will prevent the evaporation of ink contained in the ink bottle.

A further object of this invention is the provision of a device of this character which is simple, durable and inexpensive in construction and which is thoroughly practical and efficient in use.

In the accompanying drawings:

Figure 1 is a sectional view through an ink bottle with the present device attached thereto.

Fig. 2 is a perspective view of the present device per .96.

Figs. 3 parts.

Referring to the drawings, there is provided a stopper for an inkwell 6 or the like, including a body 5 having the longitudinal bore '7 for the reception of the sleeve 8 which is provided at its lower end with the flange 9, the upper end being projected above the stopper and provided with the bead 10.

Mounted upon said sleeve adjacent its upper end and limited from displacement therefrom by the head is an annular washer or plate 11 which is attached by fastenings 12 to the upper end of the stopper.

liilounted telescopically within the sleeve and for sliding movement therein is the pen receiving cylinder 13. An exterior annular flange 14 is formed on the upper edge of the cylinder 13 and arranged in close relation with the inner surface of the sle ve 8 for facilitating the guiding of the sliding movement of the cylinder within the sleeve. Surrounding said tube is a coil spring 15 which abuts the flanges 9 and 141 and normally and at are detail views of various holds the pen receiving tube with its upper bead slightly above the upper end of the main sleeve. It is to be appreciated that the two flanges 9 and 14: cooperate for guiding the sliding movement of the cylinder.

The lower end of the pen receiving tube is provided with plurality of openings or slots 16, while attached to the lower end is a disk 17, a gasket 18 being disposed upon the upper face of said disk about the tube so as to abut the flange 9 and thus close the stopper so that under normal conditions the ink within the well cannot evaporate.

From the foregoing description it is evident that when a pen point is inserted within the tube, and the disk upon the lower end thereof is contacted, that the same will be moved against the action of the spring to present the openings to the ink within the well, so that such ink will flow to the pen .point thus exposed.

The release of the pen point will cause the automatic closing of the present device, so that. no evaporation is possible through the stopper.

What I claim as new is:

A stopper for inkwells including a tubular resilient body, a washer carried by the upper edge thereof and in alinement with the inner and outer edges, a metallic sleeve engaged within the body and having a bead on the upper edge thereof for engaging the washer so as to support the body, an annular flange on the lower end of the sleeve, a pen receiving cylinder slidably mounted within the sleeve and arranged in close relation with the flange and having a plurality of slots in the lower edge thereof, an exterior annular flange on the upper end of the cylinder and arranged in close relation with the sleeve, a coil expansion sleeve disposed about the cylinder and having the respective ends abutting the flanges, the flanges also serving to guide the sliding movement of the cylinder, and a closure disk carried by the lower edge of the cylinder and having a gasket concentric of the cylinder and working against the sleeve.

In testimony whereof I aflii: my signature.

ISSAC LAUTMAN.
